Our primary impact crusher blow bars are produced from specially alloyed high manganese and high chromium castings. They offer exceptional resistance to intense impacts encountered during the initial crushing phase. Through precision heat treatment processes that comply with European and global standards, our parts achieve high surface hardness and core toughness. Compared to standard domestic castings, they offer at least 3 times longer service life. Each product is subjected to chemical analysis, microstructure inspection, and surface hardness testing prior to dispatch. (PDK-1)-(PDK-2)-(PDK-3)
